Specification of Letters Patent. Pa,tenj;ed lljy 16 1916,

Application filed December 22, 1914; Serial No. 878,578.

To all whom it ma concern:

Be it known t at we, FRANK E. WATTS and DONALD T. HASTINGS, citizens of the United States of America, residing Detroit, in the county of WVayne and State of Michigan, have invented certain new and useful Improvements in Lubricating Systems, of which-the following is a specification, reference; being had therein to the accompanying drawings.

The invention relates to lubricating systems for engines, and has among the objects thereof to provide a simple and eflicient system for lubricating various parts of the engine, and further, to reduce the number of parts required to-efi'ect a proper distribution of the lubricant.

Other objects of the invention will more fully hereinafter appear. v

The invention resides in the peculiar construction, arrangement and combination of parts as hereinafter set forth and particularly pointed out in the claims.

In the drawings,Figure 1 is a top plan view of a crank case having the improvement applied thereto; Fig. 2 is a fragmen tary sectional side elevation of an engine casing embodying the invention; Fig. 3 is an end elevation; Fig. 4 is a section on the line 4& of Fig. 1; and Figs. 5, 6 and 7 illustrate certain details of construction.

A. designates the crank case, B the crank shaft bearings and C the pan or bottom of the crank case. The crank shaft hearings in the construction illustrated are formed in partitions or divisional walls Din the crank case, three of such partitions being shown in? the construction illustrated. Arranged in.- the partitions D are bearings E for the cam shaft, and in order to simplifythe lubricating system, a construction is provided in which the bearings for theQcam shaft receive their supply of 'lubricant jfromithat fed tothe crank shaft bearir'lg sL 1 Referring more in detail to the one en'1- bodiment of the injvention shown in the drawings, F is a tube extending longitudinally of the crank case, and cast in the partitions D, and G are passages in the partitions establishing communication between the tube and the crank shaft bearings. Each 1}){21Itltl011 is provided with a second passage extending between the crank shaft hear ing and the bearing E for the cam shaft,

The bearings for the crank shaft include bushings I which are so constructed as to allow a portion of the lubricant fed through the passage G to pass to the interior of the bushing ai'fii to establish communication between the passages G and H, so that a portion of the lubricant fed to the crank shaft j hearing will. also pass to thebearing on the 6am shaft.

sections are channels N and 0 extending completely around the bushing and-connecting each of the a; ertures L and M with the channels N and I are channels P and Q. Thus the lubricant from the passage G will discharge through the aperture M and onto will also pass fromthe aperture M by way of the channels N, O, P, and Q to the aper ture R, and from the latter-to the conduit lubricant to flow up the passage H'to the cam shaft bearing.

In the structure shown; the tube or con- ,duit F is' connected through the medium of passage 5 formed 'in a .boss T through B-ivhich the tube extends, with a chamber R. MU is a conduit leading from the chamber R to a pocket V on the inner face of the flywheel housing W. This pocket is shown as oftapering or Wedge-shape form, the large end being substantially the fullwidth of the Qthat portion of the crank shaft journaled hire the bearing, and a portion of the lubricant periphery of the fly-Wheel X andpositioned i l in -close proximity thereto. quantity of lubricant is maintained in the fly-wheel housing so that the lower f p ortion of the fly-wheel is immersed therein .By

The flywheelin effect forms a punippfor forcing the liquid through the conduit'U to the chamber R and acts to place the. lubricant under suflicient pressure to cause the lubricant. to readily flow through the several conduits and channels.

At the'end of the crank case opposite the fly-wheel housing is a housing A within which are arranged the chains B and C for driving the cam shaft, magneto and other accessories. These chains are preferably lubricated through the medium of the conduit F. In the structure shown in Fig. 3 the conduit F is provided at the end thereof vwith a branch D arranged to discharge.

The inner Leading from the chamber R is a conduit H that communicates with a bore orpasend of the bore I opens into a chamber ,K within which are arranged valve stemsv L, the latter being operated in the" usual manner from the cam shaft M.- The chamber K is oil tight and designed to hold a "suflicient quantity'of lubricant to properly lubricate the joint between the valve stems L and the valve-operating rods N. The

height of the lubricantwithin the chamber K is regulatedby means of a pipe or conduit O which has theupper end extending the desired distance above the bottom 'of the chamber L. -Oil discharging fromthe conduit O returns to the crank case, as will be readily understood upon reference toFig. 5.

In use, during the rotation of the flylwheelfoil will be fed from the fly-wheel housing by way of the conduit U to the ch fiber R. A portion of the lubricant will pass cm the latter through the passage S "to:the conduit F and will be distributed to the bearings through the medium of the passage G. A portion of the oil fed to the bearings will pass into the conduit H and from the latter to the cam shaft bearing E.

Lubricant, will also discharge from thechamber B through the pipe H and bore I into the chamber K. Lubricant will collect in this latter chamberuntilit reaches the height of the conduit 0, any surplus-v zage draining back into the crank case.

While the preferred form of the invention has been illustrated and described, it ist-not desired to limit the protection to the particular structure illustrated.
